In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 8th, 2013, and during its 51.680th orbit around the Red Planet, we can see a portion of a small Unnamed Channel that is located in the Southern Side of the Martian Southern Region known as Tyrrhena Terra (a large and heavily cratered area, centered to the South of the Martian Equator and immediately North/East of the huge Hellas Impact Basin).

Tyrrhena Terra covers approx. 2300 Km (such as about 1428,3 miles) at its broadest (---> largest) extent and it was so named after a so-called "Classic Albedo Feature"; it is located in the Mare Tyrrhenum Quadrangle of Mars and it is a typical Region of the Southern Martian Terrae, characterized by heavily Cratered Highlands and Rugged (---> rough and irregular) Terrains; Tyrrhena Terra also contains, among other interesting Surface Features, the large Volcano known as Tyrrhena Patera (which is one of the oldest Volcanoes of Mars). Furthermore, its largest Impact Crater is the famous Herschel Impact Basin and, last, but not least, Licus Vallis and the Ausonia Montes are other two Major Features of this extremely rough Southern Martian Region.

This frame (which is a crop taken from an Original Mars Odyssey Orbiter, Map-Projected b/w frame published in the NASA - Planetary Photojournal with the ID n. PIA 17510) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
